java.util.ConcurrentModificationException: null

[Kettle5000]

After a damn looooooooooooooooooong investigation
we found out that your mods, this library, enhanced visuals, ambient sounds are causing random crashes to happen
those have been detected by modernfix but even this mod cant handle those crashes sometimes

if you need more info:

https://github.com/embeddedt/ModernFix/wiki/registerReloadListener-called-on-wrong-thread

i got the exact same crash as expressed here:
embeddedt/ModernFix#512
and when i checked the logs, modernfix said this

[17:55:00] [Worker-ResourceReload-16/ERROR]: A mod is calling registerReloadListener at the wrong time. This will cause random concurrency crashes when ModernFix is not installed. Please report this to them. If you are a modder, refer to https://github.com/embeddedt/ModernFix/wiki/registerReloadListener-called-on-wrong-thread for more information.

oh just realized some people already pointed this out but seems like enhanced visuals is the only mod left to update to fix this issue
